v BRIDGE GAlBLESPINNING APPARATUS Application filed January 30,1931. 'Serial No. 512,458.

Thisinvention relates to cable spinning apparatus such as used in spinning parallel bridge cables,-the object of the "invention being to provide a more efiicient guiding of the spinning wheel in passing guiding sheaves and a more efficient control of the guiding sheaves and traction rope and by which a higher spinning speedis made practicable.

In accordance with the present invention, the guiding sheaves on which the spinning wheel traction rope .runs for support and guidance through the span are mounted to.

swing sidewise and preferably supplied with guiding members coacting with the spinning wheel carrier tolassure the properposition of the guiding sheavesrelatively to the traction rope and spinning wheel carrier in case of sway of-the tractionrope or carrier. The

spinning wheel carrier, also, is preferably mountedtoswing freely sidewise on the traction rope so thatthe'swinging of thecarrier aids in assuring its proper position in passing the guiding sheaves. The upper guiding sheaves, also, are preferably mounted to rock longitudinally of the traction rope so. as to maintain their'proper positionand equalize the rope pressure on the sheaves. v

.F or a full understanding of the invention, a detailed description of constructionsof preferred forms embodying the invention will now be given in connection with the accompanying drawings forming a part :of thls specification and the features formlng the invention then specifically pointed out in the claims.

Referring to thedrawings, A is the carrier be understood that either a single spinning wheel or morethan two spinning wheels may be carried by frame A.. C is thetraction rope on which the spinning wheel carrier is mounted to swing free'ly,as described hereafter. ',D,

.Darelower guiding sheaves, on which the traction rope runs and E,'E the usualguiding sheaves above the traction rope.-- All the set of guiding sheaves .D, D andfE, E are shownas mounted on a supporting frame F securelymounted on a bent G, which maybe used inlaying the cable is supported. The frame F may be of anysuitableconstruction,

' but isshown as a skeleton frame formed of angle bars for strength.

The frame A carrying the ,spinningwheel the tramway or wheels B,=is shown'as a skeletonmetal frame and is supported from the traction rope C so as to swing freely thereon while being driven thereby, and to accommodate itself to bends in. the tractlon rope and perm1t accurate adjustmentlongitudinally of the traction rope asgfollows: Frame A is carried at the end by links .10 from end supports 11, a

seriesof, holes 1 forzconnection ofthese links at different points longitudinally of the traction rope for adjustment being shown, and these end supports 11 are swung from the traction rope by arms 2 having at their ends sleeves3, preferably split for convenience of application to the traction rope,,which sleeves I are loose on the traction rope soas to swing; freely thereon. Intermediate'of the end supportsll, the frame A is supported from the.

traction rope by support 12 having a vertical slot and pinconnection to the frameA soas to permit of vertical movement of the frame I on bending of the traction ropeandthissup- .portl2 is swungon the-tractionropeby arms '5 carryingsleevesrii on the tractionrope,sinn- 'lar toithesleeves. 3, by which support llis.

mounted thereon. .Thezfr'ameA is driven by the traction rope through one or-more sleeves 6 securedtothetraction rope ,with a series of loose filling sleeves 7 between the support sleeves 3'and the driving sleeves .6. At the bracket 1 1 with the guiding mounted on stud 15 to swing sidewise in arms 9 forming part of the frame F, and these sheaves D, D, as shown, are inclined downward and outward away from the spinning wheel carrier, so as to allow the latter to pass freely between the sheaves. The upper sheaves E, E, also, are carried by the swinging bracket 14, being mounted thereon by arms 13 on brackets 18 bolted to bracket 14; by bolts 19. Each of the sheaves D, D preferably carries uides 16 extending forward and rearward rom the inner surface of the sheaves at their axes, these cam guides 16 preferably being formed, as shown, of a metal platepassing over the inner surface of the sheaves and inclined outward at both sides of the sheaves to form the guides 16 and carried b and secured at its ends to the bracket 14. he guides 16, also, preferably are supported at the center of the plate forming them by being secured to the ends of the studs 17 in the brackets 14 in which the sheaves D, D are mounted to rotate.

The inclined or cam portions of the guides 16 are positioned to be engaged by a support 11 of the spinning wheel carrier on movement of the carrier in either direction in case the carrier frame is swung in its travel out of line with the traction rope or the guiding sheaves are swung sidewise with the traction rope relatively to the spinning wheel, and thus the sheaves and the spinning wheel carrier and spinning wheel will be brought into proper relative position for the spinning wheel carrier to pass between the sheaves D, D. These guides may be omitted and contact of the wheel carrier with the sheaves or gravity relied on to position the parts.

The construction shown in Figures 4 and 5 is the same as that shown in Figures 13 and above described, except that the upper guide sheaves E, E are mounted to rotate on a rocking carrier 20 formed of side bars straddling the traction rope and lower guide sheaves and pivotally mounted on studs 21 in the opposite arms of the bracket 14. The upper guide sheaves E, E thus rock with any bending of the traction rope C from the posi- Figure 5 to that tionshown in full lines in to maintain their shown in dotted lines so as bearing on the traction rope under equal pressure, in addition to swinging with the traction rope as in the construction shown in Figures 1-3.

It will be understood that the swinging mounting of the guiding sheaves and the guides coacting with the spinning wheel carrier may be used with a spinning wheel not having the swinging mounting on the traction rope, but preferably both the guiding sheaves and the spinning wheel frame will be mounted to swing, as shown and described herein. The inclined guide sheaves and mounting of the spinning wheel carrier forms no part of the present invention except in combination with the guide sheave mounting but in themselves form the subject matter of a separate application.

It will be understood that the invention is not limited to the particular form or arrangement of devices shown, but that many modiiications may be made therein while retaining the invention as defined by the claims.
